To all who/7t it may (HI/.f'f'l'll: 5

Be it known that 1 Clint. LAYUPK, a'suhject of the King of Prussia, German lfhn- 5 peror, and residing at Berlin, German Empire, have invented certain new and uset'ul Improvements in Mixing and Kneading Machines, of which the following is a specification.

This invention relates to a mixing and kneading machine for dough-like and other substances, which machine has mixing and kneading arms set in oscillation or means of cranks and mowd up and down ny a lever.

The characteristic features oi" the invention consist in the up-and don'irmoving single or double armed lever being only pivotally, but not displace-ably.mounted on axis of rotation and carrying the rocking axis of the mixing and kneading arms without separate guides and also in the method oi.

connecting the trough with the kneading machine in conjunction with a mechanism for lifting the trough.

Several forms of construction ol the machine are shown in the accomp n .'ing drawings, Figure 1 being a side view and partial section of a term cl constrncticn cl tie machine intended for mixing ai:d kneading-niachines of large dimensions; Big. 2, a side of a ino'di'lied form of construction of the means for operating the mixing and kneadin arms; Fig. 3, a side view of the trotiglneari" uncoupled from the machine and it Wiiit ing-up mechanism when the kneading-trou is elevated or drawn up. Fig. l is a idevie and partial section, on an enlarged sc le, oi the coupling device shovgn in.

The rocking axis 1') oi each mixing and kneading arm a is carried h a lov n, adap ed to be rocked up and down on a "i: A of rotation d. The mixing and kne arms 0 are rocked to and fro on ti. a rotation b by means oi cranks Ii: and p rods g. The rocking ol the lever (t, 'nri ving the mixing and kneading arms 0, is operated by means of a crank f, which revolves twice as fast as the c sit-res couylin sition oi the also "or \wi 'anks It, whereby the path of h I movement o'l t e k. ending-arms described in in former Cnitcd States Patent No. $05,020 is 'n'oducrd. The c 'anks f and 7t are operated in a similar manner to that descrihed in the said patent by toothed Wheels is, l, in, o, r, and '11.

Fig. 1 siovvs the lover a as a single-armed lever, and 2 as a taro-armed lever. Accordingly in Fig. .l. the mixing and kneading arms c are double. and in il ig. 2 single, armed levers. and tl: e"pushrods g in Fig. 1 engage with the upper end of the arms 0, While in Fig. on the other hand, they engage with the single arm heneaih its point oi oscillaiion h, ahereh vin noth cases the same kind of movement of tite lower ends oi. the kneading- :u'ins is produced.

in il i 1, 3, i. and 5, i is a shalt rcvolubly mounted in the frame n of the machine and both lor lirnilv counling the kneadeari'iz gt 1 with the l'r ame a ol the and. kneading; machine and also for up the kneading-trough t. On both -sleeves j are last on this shalt, which sleeves are each provided with a ilat t-eneii part on their periphery. in the couplin iiion. in which the kneading-trough carriage i heh connected to or .mounted on the underlrnme a at the kneading-machine, 2*" 1, the round part of the sleeves b is in engai, "rt with a recess p in the holdi ing-holts: q, which iiti into aljttsting-ltoles ol' the hnr .s' ol the tnnigh-carriage. in this pocoupling the engagement of the coii "vlii1; ;-.-=l eves j in the recesses p is secured by means et a intehet-xrhcel n, Fig. -:l-, last on the shaft i. and a tnvv'l at, mounted on the bar vvitn iilis ran-i avitcel. This 1.1;.- ihi\.'ing-c;l.nk 2 nrounted wing downward by reason and treating the shalt 'i. lrlr to a; The the crank 12 in such 1 i hu s dcnnu'nid in the uncouplis sun as the trough-carto the undctlrame n of kiiii i and the coupling- "not beneath the rep= 'hclts ahcut a quar- (l1ii'1! it the cienk y in. the direction of 1 f -l snliices to bring I i550 sleeves j into en T crsses y) el the retainthe coup hein eiiecicd in the manner shown in Fig. l. s

no sleeves y' of the trough-carriage cannot then escape from the bolts In order to uncouple, it is necessary to with raw the pawl 20 from the ratchet-wheel and turn the crank y in op posite direction to the direction indicated by the arrow in Fig. 4 until the round surfaces of the sleeves emerge from the recesses 19 oi the bolts Q and the fl 'encd parts the sleeves lie underne i 1 The bolts 1 are also further inten ed to prevent the lmeading-trcugh when the trough-c connected with. the kneading being lifted by the kneadi ..s dur ing the operation of kne ding. This object is attained by projections 2 being provided on the lmeading-trough, over which projections the bolts q engage, and t prevent the lmeading-trough being liited. A toothed Wheel 1 is mounted on the shait'i,w1";ich wheel gears with a toothed wheel 3, fast on the winding-drum 2. In order the supporting-arm 4 for the cord-pulleys 5 nlaynot be in the way during the coupling oi' tne trough carriage to with the kneadin -machine, they are adapted to be turned on the snait 6 down into the dependent position shown in Fig. 1. In order that the arm 4, with the cord-pulleys 5, may not encounter the ground in eir dependent position, the arns 4 are provided with a contact-surface 7, which in the turneddown position of the ar s bear ag ir t the bars 8 of the trough-earl age and re s the arms in their inclined pCSlLl n. If, however, the arrrs 4 be turned up nto the pcsit'en shown in Fig. 3, after the release of the coupling of the trough-carriage torn th kneading-machine, the slots 8 oi these arnis slide over the shaft 6, while a second contact-surface 9 on the arms also bears against the bar- .9 and is thus supported in ere cted position.

In Figs. 6, 7, and 8 brackets 10, situated on both sides of the trough t, are removably mounted on the frame n of the machine by overlapping the base of the frame at 11 or in other suitable removable manner. The

brackets 10 are provided with screw-clamps 12, by means of which when the brackets 10 are placed on the frame it of the machine the machine may be screwed to a table-top or the like 13, so as to be brought into use. Each of the brackets 10 contains a horizontal guide 14, which is broken in the middle in such a way that the tr0ugh,wl1ieh is provided on each side with two projecting supports 15 1 5, may be lifted from below into the guides 14, (see the position shown in dotted lines of the trough 25 in Fig. 6,) the rear projecting supports 16 of the trough t being able to enter the guides 14 through the central interruptions or openings in the latter. The trough t is then pushed back (in Fig. 6 to the right) into the guides 14 until it has assumed its correct position therein, and then the trough is carried in the guides 14 by its projecting sup ports 15 16 and is thereby attached to the machine in the necessary way. Any dis placement of the trough if during the working of the machine in the guides 14 may be prevented by means of pins 17 or the like inserted in the guides, which pins may be passed through the front projecting supports 15 of the trough t and throught he guides 14. In the reverse operation by displacing the tro-igli tforward (in Fig. 6 to the left) until the rear projecting supports 16 of the trough lie over the central interruption or the guides 14, and by then moving the trough downward, the trough is removed from the machine. It is thus possible to easily bring the trough into connection with the machine and again separate it therefrom without the mixing and kneading arms 0, which project into the trough, having to be removed but, on the contrary, these arms 0 may remain in the position shown in Fig. 6, in which they extend into the trough, and also there is no necessity to turn upward the entire mechanism for moving the kneadingarms together with the latter. Atter the removal er the trough from the brackets 10 and the withdrawal of the latter from the machine-"frame at these parts may be suitably laid beside the machine and conveniently tr: nsported and stored with the latter. Mixing and kneading machines of small dimensions may thereby be made as small as possible for household and like purposes.

The projections 15 and 16 for supporting the trough may be provided in any suitable manner, either by separately riveting them on, as shown, fastening by means of screws or other separate and suitable attachments of these projections to the trough-wall, or even by simply flanging round the wall of the trough to form pr ijecting supports. Simi larly any suitable way of forming the guides 14 may be adopted instead oi being formed, as shown, by ribs formed on the brackets 10. They may also be formed as partial bayonetslots suitably formed therein. Vice versa, the projections 15 may be formed on the brackets 10 and the guides 14 on the trough t. The attachment of the trough to the mixing and kneading machine may also be effected by first inserting the trough in the brackets 10 and then attaching the brackets 10 to the machine-frame a.

Figs. 9, 10, and 11 show three further separate forms of construction of the attachment of the trough t to the brackets 10. In Fig. 9 a short jaw or mouth like guide 14 is provided on the front end of the brackets 10, and the trough t has two corresponding support-pins 15 at both sides in front. By means of these pins the trough t is inserted in the mouth or jaw like guides 14. At the rear end there are eyelets 16 in the trough, which may, if desired, also be "formed by hanging round the material of the trough-wall. By means of bolts 18 or the like, which are inserted in the eyelets 16 of the trough and in holes in the bIflCliGtS 10, the trough may he held last at r the rear end of the braekets.

In Fig. 10 the brackets have 1axv-hke guides l t in front and at the r ar, in high 1 guides the support-pins 15 and .16 oi the In order thatthe trough r are 1nserte-:.t.
